NIHON KOHDEN Neurofax EEG System Analysis Report
Device Identification and Brand Model Information
The images show a comprehensive electroencephalography (EEG) system mounted on a mobile transport cart. The system consists of a monitor, keyboard, mouse, an EEG headbox/amplifier, a computer tower, and two power/isolation units.
- EEG Headbox/Amplifier Brand-Model: NIHON KOHDEN Neurofax
- Isolation Unit Brand-Model: NIHON KOHDEN SB-202Z
- Monitor Brand: PHILIPS
- Other Units: The brands of the computer tower and the other power unit could not be clearly identified from the images.
Authenticity Assessment
Upon examining the NIHON KOHDEN logos on the device, the print quality of the labels, and the general craftsmanship details, the impression is that the product is authentic. The CE mark on the isolation unit also supports this assessment.
Usage Areas
This NIHON KOHDEN Neurofax EEG system is a medical device designed to measure and record electrical activity of the brain. Its primary areas of use include neurology, electrophysiology laboratories, intensive care units, and sleep disorder centers. It is used for purposes such as epilepsy diagnosis, sleep studies, monitoring brain functions, and evaluating various neurological disorders.
Quantity Information
The quantity information for the products and accessories identified in the images is as follows:
- Mobile transport cart: 1 unit
- Monitor: 1 unit
- Keyboard: 1 unit
- Mouse: 1 unit
- EEG headbox/amplifier: 1 unit
- Computer tower: 1 unit
- Isolation unit: 1 unit
- Power unit: 1 unit
- Adjustable arm: 1 unit
- Cables: Numerous (power, data, and electrode cables)
General Condition and Physical Deformation
Although the device has been used, it is in good condition. No significant scratches, dents, cracks, or discoloration were observed on the casings of the monitor, keyboard, mouse, computer tower, isolation units, or the EEG headbox. There is slight dirt and signs of use on the wheels of the transport cart. Slight yellowing or dirt may be visible on the cables, but there is no significant physical damage.
Mechanical and Electronic Component Inspection
Mechanically, the wheels of the transport cart appear sturdy and functional. No fractures or cracks were detected at the joints of the adjustable arm. The optical drive cover of the computer tower is intact. The switches (POWER, BREAKER) on the power units appear functional.
Since the internal structure of the electronic components is not visible in the images, a detailed analysis could not be performed. However, viewed from the outside, the casings of all units are intact. The electrode inputs and the impedance check button on the EEG headbox have a solid structure. The power input and switches on the isolation unit are also in good condition.
Accessories and Socket Inputs
Power cables, data cables, and electrode cables connected to the EEG headbox are included with the system. The EEG headbox contains numerous electrode inputs (L, R, X1-X6, RESP F, RESP C, RESP A, BP1-BP3). An AC power input is visible on the isolation unit, and USB ports along with an optical drive input are visible on the computer tower. No products with an expiration date were found among the accessories.
Battery Status
No internal or external battery belonging to the device was identified in the images. It is understood from the label information and power inputs that the device operates on mains electricity.
Label Information and Meanings
The information on the labels found on the products and their meanings are listed below:
- Information on the EEG Headbox/Amplifier:
- Brand Logo: NIHON KOHDEN. This indicates the manufacturer of the device.
- Product Name: Neurofax. This refers to the model series of the device.
- Inputs: L, R, X1, X2, X3, X4, X5 RESP F, X6 RESP C, RESP A, +BP1, -BP1, +BP2, -BP2, +BP3, -BP3. These indicate different electrode and physiological signal input points. “RESP” may refer to respiration-related inputs, and “BP” may refer to bipolar inputs.
- Electrode Positions: FP1, FP2, F7, F3, Fz, F4, F8, T3, C3, Cz, C4, T4, T5, P3, Pz, P4, T6, O1, O2. This section specifies the standard placement points for EEG electrodes according to the international 10-20 system.
- Impedance Check: SELECTOR (kΩ) and IMPEDANCE CHECK button. This feature is used to check the contact resistance (impedance) of the electrodes with the skin. Low impedance is important for higher quality signal recording.
- CE Mark: Indicates that the product complies with European Union health, safety, and environmental protection standards.
- Information on the Isolation Unit (on the right):
- Brand: NIHON KOHDEN CORPORATION. Indicates the manufacturer.
- Model: SB-202Z. This is the specific model code of the unit.
- Serial Number: 00022. This is the unique identification number of the device.
- Input Voltage: 220-240V 50/60Hz. Indicates the electrical grid specifications required for the device to operate.
- Breaker: BREAKER 4.5A. Specifies the amperage value of the circuit breaker that provides protection against overcurrent.
- Power Supply: ~AC SOURCE. Indicates that the device operates on alternating current (AC).
- Manufacturer: Made by NIHON KOHDEN CORPORATION. Indicates the place of production and the company.
- CE Mark: Indicates that the product complies with European Union health, safety, and environmental protection standards.
- Information on the Power Unit (on the left):
- Brand: NIHON KOHDEN. Indicates the manufacturer.
- Switch: SINGLE, POWER. Indicates that the device operates in single mode and identifies the power switch.
- Label on the Adjustable Arm:
- Caution: CAUTION (in Japanese and English). English text: “Do not touch the lamp immediately after use. The lamp is hot and may cause burns. Do not touch the lamp with wet hands. Risk of electric shock.” This warning informs the user about the risk of heat and electric shock in case a lamp is present on the arm.
- Handwritten Label on the Computer Tower:
- Text: “EEG Program”, “73 istemli 500 gb”, “windows 10 pro”. This label indicates that the computer contains EEG software, has 500 GB of storage with 73 clients, and uses the Windows 10 Pro operating system.
Screen Analysis
Since the screen of the PHILIPS brand monitor in the images is turned off or black, no text, warnings, menus, or value information could be detected on it.
Dimensions and Compatibility
There is no direct information in the images regarding the dimensions or size of the product. However, the fact that the system is mounted on a standard mobile transport cart indicates that it can be easily moved in clinical or laboratory environments and is compatible with different workspaces. The monitor and computer tower are of standard sizes compatible with general desktop computer components.
Year of Manufacture
There is no direct information regarding the year of manufacture on the device labels or in the images. However, the design of the monitor, the presence of an optical drive in the computer tower, and the general aesthetics suggest a production period from the late 2000s or early 2010s.
Documents
No invoices, warranty certificates, user manuals, or other documents belonging to the device are visible in the images.
Usage Duration
There is no information regarding the usage hours or total operating time on the device screen, labels, or any documents present in the images.
